IMPROVEMENT IN WIRE FABRICS.

Specification forming part of Letters Patent No. 1 12, 150, dated September 2, 1873; application filed June 1873.

CASE B.

To all whom it may concern:

- Be it known that I, WILLIAM CHARLES EDGE, of the city of Newark, in the county of Essex and State of New Jersey, have invented an Improved Wire Fabric, of which the following is a specification:

Figure 1 is a face view, onan enlarged scale, of my improved wire fabric. Fig. 2 is a sectional view thereof on the line 0 c, Fig. 1.

Similar letters of reference indicate corresponding parts of the figures.

The object of this invention is to produce a wire fabric of greater strength than the same has heretofore been made. The wire fabric herein referred to is more generally used for articles of jewelry, and is woven on machines substantially like the one described in my Letters Patent dated the. 23d day of April, 1872. As described in the said patent, and as usually made, the links, or rather the bent loops of the wire, are passed through the links or bent loops projecting from the edge of the fabric, and thus constitute an addition to such fabric, the process of weaving being indefinitely continued by passing the loops of the additional wire through the loops projecting from the fabric as far as finished. In such fabrics, therefore, a single and simple connection was produced. Such wire fabrics are now, under an invention made by me, to be considerably used for the manufacture of watch chains, bracelets, &c., for which purpose the fabrics are out into narrow strips, and then bent; and I find that it is advisable to increase the strength of the fabric, and especially to provide a more firm connection of the parts than that formerly given, so as to prevent the fabric from becoming unraveled when out into very narrow strips. For this purpose, instead of passing the loops of the bent wire through the last remaining loops of the fabric, I pass each loop of the wire through two loops of the fabric, so that thus a firmer connection of the parts is obtained. From Fig. 1 this will fully appear, the loops a formed on the last wire being each passed through the outermost loops b, and through the next inner loops d of the fabric that was completed before a was formed or applied. It is quite evident that by thus passing each loop through two a firmer connection of the parts is obtained; and if the fabric be out on the line 0 c, or at any other part in the same direction as the line 0 c, the

strips detached by such cutting will still remain sufficiently firm for all practical purposes, and not be subjected to the danger of becoming unraveled. Fig. 2 also clearly shows how the loop a is passed through I) and cl.

The wire to be used in this fabric is, preparatory to application, bent into a zigzag form between two toothed wheels, or by other means, substantially as described in my aforementioned Letters Patent that is to say, made to form alternately upwardly and downwardly, or inwardly and outwardly, projecting loops, each of which is then made to pass through two other loops, in the manner shown and above described; The ends of the out-v wardly projecting loops are expanded subsequent to application, in order to prevent their withdrawal from the fabric.

I claim- A wire fabric constructed with each loop a passing through two loops, 1) and substantially as herein shown and described.

WILLIAM CHARLES EDGE.
